This study was carried out to investigate the effects of imported 0.25 ml straw frozen semen on fertilizing capacity after artificial insemination. A total of 57 ewes of Corriedale were inseminated at the Namwon Branch, National Anirnal Breeding Institute. Lambing percentage and twinning percentage were 12.3% and 114. 3%, resepectively. Average weight at birth and weaning of 120 days old were 4.5kg and 21.9 kg, respectively. Gestation period was 152.6 days.

Romer류의 내생적 성장모형과 신고전학파의 성장모형을 통합한 Jones(1997, 1998a)에 의하면 장기균형성장요인의 기여도가 예상보다 작고 여러 단기요인의 성장기여도가 큰 것으로 나타났다. 본고에서는 기술이용능력과 모방노력의 개념을 도입하여 Jones모형을 수정하고 이를 이용하여 한국의 성장요인을 분해한다. 이에 따르면 대GDP 투자비중, 연구인력비율 및 취업자 교육연수의 증가 등 이행경로상의 단기요인이 지난 30년간의 노동생산성 증가의 78%를 설명하고 있으며 균형성장경로 요인의 기여도는 22%에 지나지 않는다. 자본축적의 뒤를 이어 R&D 투자 등 새 단기요인의 역할이 증대되면서 우리나라의 경제성장률이 크게 하락하지 않을 것으로 예상된다.

This study examined the effects of clarification training on conversational breakdowns and repair strategies of 3 school aged children with ASD. Clarification training provided to the participants during playing the barrier games. The results found that the occurrence of conversational breakdown was decreased in terms of overall and types. The occurrence and appropriateness rates of repair strategies were increased among all participants. Based on the results, 'clarification training' used in this study can be an effective method to train children with ASD for appropriate repair strategies in conversation.

Background & Object: Basic daily activity screening tool such as the Modified Barthel Index (MBI) has been used commonly in rehabilitation clinic and community based rehabilitation setting. Previous studies have shown the significant relations between the level of daily activities and driving ability on stroke or elderly people. However, there is a lack of studies to investigate the usefulness of MBI on prediction of driving ability for stroke patient. This study was to predict driving abilities of stroke survivor using Korean version Modified Barthel Index (K-MBI). Methods: A sample of 48 patients with stroke in rehabilitation hospital was recruited. All participants were tested level of basic daily activities using K-MBI. The driving ability of participants was tested using virtual reality driving simulator. The predictive validity was calculated of the K-MBI among pass or fail group of driving simulator test using receiver operating characteristics curves. Results: The cut-off score of >86.5 on the K-MBI is proper sensitivity to predict on driving performance ability. Conclusion: This pilot result offers clinical reference to therapists and caregivers for reasoning on driving recommendation period during rehabilitation stage of stroke survivors. Further studies need to identify prediction using real on-road test in a large population group.

The purposes of this study were to examine the general tendency of knowledge and problem solving abilities of children to cope with climate change and to find out whether there is a difference in the ability to cope with climate change based on the gender and age of young children. For this purpose, 129 children aged 5 and 6 who are attended in day care center in Seoul and Gyeonggi area were selected. We used 10 questions to measure climate change response knowledge modified environment conservation knowledge checklist and used five problem solving situations to measure climate change response problem solving ability modified safety problem solving ability test item. The collected data were analyzed using mean, standard deviation, two-way ANOVA, and Pearson's correlation coefficient. As a result, 6-year-old children's knowledge of climate change response and ability to solve climate change problems was higher than that of 5-year-olds. There was no gender difference in knowledge of climate change response and ability to solve climate change. The higher the knowledge level of children's response to climate change, the higher their ability to solve climate change response problems. The results of this study confirmed the association between children's knowledge of climate change response and problem solving ability and showed that a more systematic curriculum for improving knowledge and problem solving ability for preventing climate change needs to be provided to children.

정보화 시대를 맞이하여 정보의 홍수 속에서 지리교사들은 정보 획득 능력에 있어서 큰 차이를 보여주고 있다. 이와 같은 현실에서 정보 접근 능력이 떨어지는 교사를 탓하기보다는 산재해 있는 지리정보를 되도록 한 곳에 통합해서 교사에게 지름길을 제공하는 것이 더욱 효율적인 방안이 될 것이다. 대부분의 지리 교수-학습 자료가 전적으로 자료를 개발한 사람의 의지에 따라 만들어진 자료이기 때문에, 다른 지리교사가 사용할 경우 융통성이 부족하므로 사용자의 의도에 맞게 수정 편집될 수 있는 형태의 자료가 바람직하다.(중략)

This study was conducted to investigate the effects of modified wall squat exercise after sacro-iliac joint mobilization on balance in normal adults. The total number of subjects was 34, and 17 were randomly placed in the experimental group(EG) and 15 in the control group (CG). The subjects in the EG have conducted the 3 sets of modified wall squat exercise after sacro-iliac joint mobilization per day, 3 times a week for 6 weeks and CG did not conducted the intervention. Comparing the EG's balance pre-test and post-test this study, there was a statistical significance in WDI, CD, AC and AD. In this study, it was confirmed that modified wall squat exercise after sacro-iliac joint mobilization affects balance in normal adults.

The purpose of this study is to examine the balanced English approach program on five-year-old children's English reading and writing ability. For this study, two classes consisting of five-year-old children in HATBEAT kindergarten in D city were selected. One class was designated as the experimental group and the other as the control group. The balanced English approach program was performed on the experimental group but not on the control group. The balanced English approach program was carried out for 8 weeks. The experimental procedures were in the order of pre-test, the experimental treatment, and post-test. The result of the experiment was evaluated by comparing the pre-test and post-test results. Analysis of data was performed by ANCOVA. The result of the study are as follows. First, in the English reading ability, the experimental group was more enhanced than the control group. Also, for sub-factors of English reading such as alphabet and English word reading ability, the experimental group was more enhanced than the control group. However, in the English book reading ability as a sub- factor of the English reading, there was not much difference in the result between the experimental group and the control group. Second, in the English writing ability, the experimental group were more enhanced than the control group.

체외성숙과 수정된 돼지 난자의 체외발달능이 체외배발생 배양액인 NCSU 배양액에 0.4% BSA, 10% 혈청 혹은 아미노산(2% BME 아미노산 용액과 1% MEM 아미노산 용액)을 첨가함으로써 조사되었다. 본 실험에 공시된 난자는 체외수정 후 30시간 (2-세포기) 혹은 48시간 (2~4-세포기)에 회수하였다. 실험 I에서 0.4% BSA가 첨가된 NCSU 배양액에서 2-세포기 난자들의 배양경과시간에 따른 발달능을 조사한 결과, 배양 후 72시간 (체외수정 후 102 시간)에 상실배와 배반포기가 나타났으며, 배양 후 120시간째(체외수정 후 150시간)에도 팽창된 배반포까지만 발달하였다. 실험 II는 체외수정 후 48시간의 분할된(2~8-세포기) 난자들의 핵과 외관적 분할구와의 수적 차이를 조사한 결과, 2~4-세포기보다는 5-세포기 이상에서 핵과 분할구의 조화에 차이가 많았다. 실험III에서는 BSA, 혈청 혹은 아미노산이 첨가 혹은 무첨가된 배양액내에서 2~4-세포기 난자들의 배반포 후 부화능력을 조사한 결과, 모든 군에 있는 난자들은 팽창된 배반포까지 발달할 수 있었던 반면, 난자의 부화는 아미노산 혹은 혈청이 포함된 배양액에서만 일어났다. 더욱이 상실배와 배반포시기에 혈청의 첨가는 부화 배반포기 배의 발달을 현저히 증가시켰다. 이상의 결과로 미루어 볼 때, 배양액내에 대한 아미노산과 혈청의 첨가는 돼지 배반포의 부화를 유도할 수 있다고 본다.
